When a country music super group teams up with two talented musicans to sing a classic song, the result is sure to be amazing. Such was the case when Diamond Rio collaborated with Steve Wariner and Lee Roy Parnell in 1994 to cover Haggard's "Workin' Man Blues."

Crediting themselves as "Jed Zepplin," the group's cover was featured on an album in Haggard's honor, called Mama's Hungry Eyes: A Tribute to Merle Haggard. Other major country artists such as Brooks & Dunn, Vince Gill, and Alabama also recorded their own versions of Haggard's signature songs for the album,

Jed Zepplin's cover of "Workin' Man Blues" was one of the most popular songs in the collection, and it broke into the top 50 on the Billboard country chart. The song became an even bigger hit with fans when the group released a music video for it, which features old footage of Haggard singing on a television in the background.
